The mod author states:
"2 beautiful handcrafted Gaben shields for our lord. Craftable, temperable. Amazing! They are found under iron at the forge. This was made as a request."
And further notes, for those of you who are concerned about keeping Skyrim true-to-lore:
All this stated, oliver1706 offers his modding services to those who'd like to send him TF2 items and steam trading cards, so if you want to put your arch enemy's face on the front of a shield, send him a hat.
